Tantalum Capacitors: Advantages Considerations |

What is a Tantalum Capacitor? What makes tantalum capacitors unique is the usage of tantalum for the anode of the device. This anode is set up as one chunk of material inside of the case, which is very different from the layering style used in MLCC capacitors where the material is sandwiched on itself and then capped on the ends.

Tantalum Facts, Symbol, Discovery, Properties, Uses

Tantalum Uses. Tantalum is used in capacitors where an oxide layer formed on it acts as an insulator (dielectric) to store more charge. A thin layer of Ta is also coated on other metals to achieve a higher capacitance in a smaller volume. Due to this reason, it is suitable for portable electronic devices like mobile phones [1, 4].
